Modern...ish Vocational Testing
Holla(nd) mundo!¶
The Holland Occupational Themes is a theory of personality that focuses on career and vocational choice. It characterizes people on the basis of their affinity for six different categories of occupations. The six types yield the RIASEC acronym, by which the theory is also commonly known. The typology has come to dominate the field of career counseling and has been incorporated into most of the popular assessments used in the field.
We go through the following steps:
- Loading of example data
- Minimal exploration with pandas
- Result dashboard with plotly
You can take the test online in: https://openpsychometrics.org/tests/RIASEC/

I'd like to refresh the comercial aspect of the data world for an interview. For this I gathered a list of Key Performance Indicators to use in practice problems, scrapping from a few websites using HTTP requests, Selenium, regular expressions and XPath.
kpis = {}
for category in categories:
name = category.split('/')[-1]
print(name)
chrome.get(category)
try:
extra = chrome.find_element_by_xpath('//div[@id="featured-snippet"]/ul').text.split('\n')
except:
extra = []
kpis[name] = list(set([e.text for e in chrome.find_elements_by_xpath('//h3[@class="strong h4"]')] + extra))
sleep(3)

Con un poco de atención, podemos observar, del gráfico superior al inferior:
- El vibrato de la flauta
- El tono de la obra (C# ~554hz, Prélude à l'après-midi d'un faune)
- La melodía
